Free tool · Box trucks & small items

Will it fit the box before you say yes?

Estimate volume and weight for partials and small items. Built for cargo vans and box trucks — not a full 3D packer, just honest numbers so you waste fewer trips.

Items / stops (up to 5)

Uses a 75% packing factor for real-world gaps. Always measure door height and awkward shapes yourself.

How this helps

Partials and “small items” jobs die on bad cube math: you accept three stops, show up, and the box is full after two. This tool totals volume and weight with a realistic packing factor so you can say no before you burn half a day.

It is an estimate, not warehouse software. Door height, couches, and pallet overhang still matter.

Common questions about cube fit

Is this a full 3D packer?

No. It estimates total volume and weight against your box and payload, then applies a packing factor for real-world gaps. Awkward shapes, door height, and load order still need your judgment.

Why use a packing factor?

Items never fill every cubic inch. A packing factor (this tool uses 75% of raw box volume as usable) keeps estimates honest so three “easy” stops do not overflow the box after two.

Does weight matter as much as cube?

Yes. A light, bulky load can max volume first; dense freight can hit payload first. Check both before you commit — especially on cargo vans and smaller boxes.

Is the cube fit checker free?

Yes — no signup, no card. It runs in your browser. Pair it with the free rate calculator once you know the freight fits.
